DOOR. i

T0 (ZZZ whom, it may concern Be it known that I, FRANK F. MILLER, citizen of the United States, residing at Sioux City, in the county of Voodbury and State of Iowa, have invented certain new and useful Improvements in Doors, of which the following is a specification.

This invention relates to swinging doors and more particularly to a door for use upon barns, garages, and other similar building structures requiring a door of considerable width and one which is more or less exposed to the elements; and the primary aim of the invention is to provide a door the boards comprising which will not be liable to become relatively displaced, which would result in sagging of the door. In the construction of such doors, it is customary to employ boards which are arranged edge to edge, one above another, and extend horizontally, and in order to prevent these boards from becoming relatively displaced, it has been heretofore necessary to employ stout braces which are secured to the boards upon opposite sides of the door and are designed to hold the boards against such displacement. However, these braces add so considerably to the weight of the door that their securing means will in time work loose and allow the door to sag.

The present invention contemplates the provision of means which will in no way add to the weight of the door but will positively hold the boards comprising the same against relative displacement.

The invention also contemplates the provision of a novel hinge for the door which will permit of the door being readily dismounted and which will at the same time,

be more substantial than the ordinary leaf or strap hinges employed in mounting such doors.

As before stated, the boards composing the door are arranged horizontally and consequently, a door constructed in accordance with the principles of the invention may be cut down without trouble to fit door-openings of Various widths.

For a full understanding of the invention reference is to be had to the following description and "accompanying drawing, in which Figure 1 is a perspective view of a door embodying the present invention, parts being broken away; Fig. 2 is a top plan View Specification of Letters Patent.

of the door, one side of the door frame being shown in section; Fig. 3 is a vertical transverse sectional view on the line 3-3 of Fig. 2; Fig. 4 is a perspective view of the meeting portions of two of the boards comprising the door, about to be assembled, this view illustrating also the means adapted to be interposed between the doors to hold them against relative displacement. Fig. 5 is a perspective view of a slightly modified form of hinge.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawing by the same reference characters.

In the drawings, the door is illustrated as comprising a number of boards 1 which are disposed edge to edge and in horizontal position one above another, these boards preferably having their meeting edges formed with matching tongues and grooves, 2. As a means for bracing the boards 1 in their assembled relation, there are provided angle iron braces, of which there are preferably two, one of these braces being indicated by the numeral 3 and the other by the numeral a, and each having one wing secured by means of bolts 5 to one side of the door and its other wing projecting at right angles from this said side of the door. The brace 3 is located near the hinged side of the door and the brace 4: near the free side thereof, and these braces preferably extend parallel to the said sides of the door and consequently in parallel relation with respect to each other. Upon the opposite side of the door there are secured, by means of the bolts 5, other braces 6 and 7, the brace 6 being located directly opposite the brace 3 and the brace 7 being located directly opposite the brace 4. These braces 6 and 7 are preferably of strap metal. The bolts 5, as will be readily understood, pass through braces 3 and 6, and the braces 4t and 7 and through the boards 1 held between these braces, there being preferably two of the bolts secured through each board 1, one near the upper edge thereof and other near the lower edge.

As clearly shown in Fig. 4 of the drawings, each board 1 is formed in its under edge with a recess 8 and in its upper edge with a recess 9, these recesses registering in the meeting edges of the boards. The means provided for positively holding the boards against relative displacement is in the nature of rectangular blocks 10, preferably of wood, which blocks are arranged one within each set of matching recesses 8 and 9 in the manner illustrated in Fig. 1 of the drawing. It will be understood that the boards 1 have a tendency to slip, one over another, and that this tendency is arrested by the blocks 10 which are interposed in the recesses 8 and 9 and extend between the matching edges of the boards. In this manner, such relative movement of the boards is prevented and the door as a whole is prevented from sagging. ln order to prevent displacement of the blocks and also to conceal them, they are so arranged between the braces 3 and t3 and the braces r and 7 as shown in full and dotted lines in Fig. 1 of the drawing, it being understood that they are of a thickness equal to the thickness of the boards 1 and consequently till the space between the walls of the recesses 8 and 9 and between the braces 23 and G or 1: and 7, as the case may be. It will further be understood that the blocks 10 are so arranged within the recesses 8 and 9 that their grain will extend at right angles to the grain of the boards 1, and that consequently the blocks are not liable to be sheared by the tendency of the boards toward. relative displacement.

As before stated, the invention contemplates the provision of a novel hinge for mounting the door, and in the drawings one side of the door frame is indicated by the numeral 11, this being the side upon which the door is usually supported. One member of the hinge is in the form of a tubular pin'tle, 12, which is of the same or greater height than the door 1 and is formed near its upper and lower ends with openings 18. Bolts 14 are provided, each at one end with an upstanding hook 15 fitting through one of the openings 13, with the hook extending within the bore of the pintle 12, and the shanks of these bolts are inserted through openings in the door frame 11 and have threaded upon them nuts 16. The shank of each bolt 1%: is preferably formed with an integral shoulder which bears upon one side of the member 11 of the door frame, and r the nut 16 upon the bolt bears upon the opposite side thereof; and, as will be readily understood, this shoulder 17 serves to prevent the bolts being drawn through the member 11 of the door frame to such an eX- tent as to bind the pintle 12 thereagainst. In other words, the shoulders 17 of the bolts serve to hold their hooked ends 15 suitably spaced from the door frame member 11. The other portion of the hinge sup port for the door consists of two or more hinge members which are carried by the door and which embrace the pintle 12 in a manner to be presently explained. Each of these member is formed upon a suitable y length of strap iron which is bent at a point between its ends to form a loop 18 and arms 19 and 20. For a short distance beyond the loop 18 the arms 19 and 20 extend in paral lel relation, as indicated at 21, but beyond this point the arms 20 are bent to extend downwardly at an angle to the arms 19, as clearly shown in Fig. 1 of the drawings. These members are assembled with the door by positioning them upon the hinged side of the door with the arms 19 and 20 straddling the door, and a bolt 22 is secured through the bars 21 of the arms 19 and 20 and through the board 1 straddled by these arms. One of the bolts 5, indicated specifically by the numeral 5 is secured not only through the brace 3, brace 6 and board 1, straddled by the arms 19 and 20, but also through the end of the arm 19, this end of the arm overlapping the brace 6 in the manner shown in Fig. 2 of the drawings. The corresponding end of the arm 20 overlaps the ends of the braces 3 and 6 in the manner shown in Figs. 1 and 3, and the other of the bolts 5, indicated specifically by the numeral 5", is secured through the said end of the arm 20 as well as through the braces 3 and 6 and the said board 1. The loop 18 is in itself substantially semi-circular and is so spaced at its side from the inner edge of the door as to pivotally embrace the pintle 12.

As illustrated in Fig. 1 of the drawings, one of the above described hinge members is located at the top of the door and another at the bottom thereof, and when properly assembled upon the pintle 12 the loops 18 of these hinge members rest upon the shanks of the bolts 1 1 in the manner illustrated in Fig. 3, and these members are in this manner held against slipping down upon the pintle 12. In this manner, the door is firmly supported for swinging movement. Inasmuch as the inner edge of the door rests against the pintle 12 throughout the entire length thereof and this pintle is firmly supported in upright position upon the member 11 of the door frame, sagging of the door at its hinges is prevented.

In the form of the invention shown in .sig. 5 of the drawings, a block 23 is provided in connection with each of the bolts 14;, this block having one side recessed as t 2% to partly embrace the pintle 12 and its opposite side plain, as at- 25, to fitflat against the member 11 of the door frame. When this block is employed, the bolts need not be provided with the shoulders 17 here tofore described, and the lower edges of the loops 18 of the above described "hinge members will in this form of the invention rest against the upper edges of the blocks 23.

It will be understood that the blocks 23 serve eifectu'ally as a means for preventing cutting of the bolt shanks as the door is swung upon its hinges.

Having thus described the invention, what is claimed is:

1. A door comprising sections disposed edge to edge and having their edges formed with matching recesses opening at the opposite faces of the door, blocks disposed within the said recesses and holding the sections against longitudinal displacement with relation to each other, and means secured upon the faces of the door closing the said recesses and retaining the blocks in place.

2. A door comprising sections disposed edge to edge and formed in their meeting edges with recesses, the recesses opening at the opposite faces of the door, brace-bars secured upon the opposite faces of the door and closing the said recesses, and blocks disposed Within the recess and confined between the walls thereof and between the said brace-bars.

3. A door comprising sections disposed edge to edge and having their said edges formed with matching recesses, the recesses opening at one face of the door, a block disposed within each of the recesses, and means secured to the said face of the door and closing the recesses.

In testimony whereof I affix my signature in presence of two witnesses.
